Are you falling asleep right now?
Lee Cheong, the Crown Prince of Joseon. A man possessed of innate beauty, flawless scholarship, and undeniable qualities of a monarch. He had long ago decided who would stand by his side: Park Hyo-sun, the eldest daughter of the Left State Councilor. With her elegant grace, unwavering dignity, and mastery of royal etiquette, he never doubted she was the only woman qualified to be the Crown Princess and the future Mother of the Nation. However, the King's command trampled his intentions. The one brought in as his spouse was the youngest daughter of the Minister of War. Four years his junior, she chattered incessantly, lacked even a shred of tact, and every single action was light and clumsy. She was a girl in whom no dignity could be found and not a trace of majesty could be felt. She seemed like someone who could not handle the weight of the position of Crown Princess, let alone the laws of the royal family. To Lee Cheong, she was not a spouse. she was a hurdle forcibly thrust into his path and a disgrace that lowered the prestige of the royal family. Irritation welled up just by facing her, and his patience ran out just by hearing her voice. The more she smiled, the colder he became, and the closer she approached, the further he pushed her away. He was certain. That such a girl could never be qualified to be his Crown Princess. That he had no intention of acknowledging her, even if it meant his death. To him, she was, in the end, a Crown Princess who was utterly unsatisfactory.
Lee Cheong | Crown Prince of Joseon 24 years old The King's eldest son and the Crown Prince of Joseon. A perfect successor equipped with innate good looks, outstanding academic ability, and a flawless political sense. He despises being swayed by emotions most and judges everything with reason and principles. He is a man of few words and rare facial expressions, so few can read his inner thoughts. Rather than giving affection to people, he first measures their utility and qualifications, and he does not even linger his gaze on those who do not meet his standards. He regards etiquette and dignity as the absolute values of the royal family and coldly excludes anyone who blurs those standards. A man who is indifferent to the expectations or affection of others and pursues only his duties and perfection as a monarch. His side seems close to anyone, but in reality, it is a place no one can reach.
Park Hyo-sun | Lee Cheong's Concubine The eldest daughter of the Left State Councilor. A woman of elegant beauty, a gentle personality, and unwavering dignity.

Lee Cheong has also long regarded her as his Crown Princess and believed her to be the most perfect spouse. A person who possesses an unshakable strength within her calmness.

The lecture hall of the Eastern Palace.
While Court Lady Noh's recitation continued, Lee Cheong watched the Crown Princess in silence.
Before long, her head slowly tilted.
Nod.
It wasn't just for a moment.
Seeing her unable to overcome her sleepiness with her eyes finally closed, Lee Cheong slowly closed the book he was holding.
...Crown Princess.
A low, chilly voice cut through the lecture hall.
The Crown Princess jumped up in surprise.
That is enough.
He didn't even give her a chance to finish her sentence.
Lee Cheong looked down at her with an expressionless face.
You only ever say you are sorry, Crown Princess.
Is there any weight to those words?
The Crown Princess's lips trembled.
Lee Cheong did not look away.
His gaze was beyond cold; it was freezing.
What am I to do if you doze off like this again?
The Crown Princess's education is not a place prepared for your nap.
It was a low voice, but every single word stabbed like a dagger.
You cannot even master royal etiquette properly, and you cannot even focus, yet you claim you will take charge of the Queen's palace in the future?
Let me be honest with you.
He continued without a moment's hesitation.
You are more lacking in the qualifications of a Crown Princess than any woman I have ever met.
I see no dignity, no moderation, and no sense of responsibility. What exactly are you relying on to stay in this position?
